Question

A truck driver made this time-distance graph to show total distance traveled one afternoon.

Which explanation matches the graph?
A. The driver went 120 miles in 3 hours. After a 1 hour break, the driver drove 60 more miles.
B. The driver went 120 miles in 3 hours. After a 1 hour break, the driver drove 240 more miles.
C. The driver went 180 miles in 3 hours. After a 1 hour break, the driver drove 60 more miles.
D. The driver went 180 miles in 3 hours. After a 1 hour break, the driver drove 240 more miles.

Answer 1

That looks a lot like the rain graph from a minute ago. Are you sure you didn't attach the wrong file?

Answer 2

yup wrong graph

Answer 3

got it

Answer 4

C

Answer 5

the slope increases up till a 180 miles from 0 - 3 hours

Answer 6

then the slope is steady and has not increased in miles by any amount for an hour which suggests he had a break for that hour

Answer 7

after that there was an increase from 180 to 240

240 - 180 = 60 miles

Answer 8

Well, you can see that the graph goes up to 180 miles during the first three hours. Given that, you can rule out A & B. Then, after the 1 hour break, the graph jumps up to the 240 mile mark, but don't be fooled! The driver only moved an additional 60 miles, having gone from 180 to 240. 240-180=60.
